Hi R-help:
I'm just an old guy and new to this list... But have been using R for
years now.
I want to make a map of counties in the US with shaded colors that
depend on the level of variable "Y" that I want to map.
I have the US county and state fips codes and the Y variable.
How do I do this?
Please reply to p...@cdc.gov
Thanks,
